“…Nevertheless, the larvae fed with Rho and Chae presented larger stomachs in relation to their length by model B (SL ~ BL). According to Qi et al (2018), larvae fed with more suitable diets present relatively larger stomachs than those fed with nutritionally poorer diets. The result obtained reflect the digestive ability and the nutritional quality of the diets provided (George et al, 2008; Qi et al, 2018; Schiopu et al, 2006).…”

In fact, the average standard residuals obtained in model C for larvae fed with Rho showed a shorter arm in relation to the larval stomach, supporting the idea Rho fulfils the nutritionally requirements for larval development.…”

The nutritional characteristics of microalgae affect the growth, survival and fatty acid composition of sea urchin larvae. This study aimed to evaluate the influence of nutritive characteristics of single microalgal diets in Paracentrotus lividus (Lamarck, 1816) larval development, growth, and condition. Larvae of P. lividus were fed with three monospecific microalgal diets, Rhodomonas sp. (Rho), Dunaliella tertiolecta (Duna) and the diatom Chaetoceros calcitrans (Chae), and their development and growth were analysed until competence. Additionally, the fatty acid (FA) profile of larvae was analysed at competence and compared with the FA profile of the correspondent diet. The three groups of larvae attained competence simultaneously with differences in growth performance. The larvae fed with Chae attained the largest stomach and the shortest post‐oral arm. The larvae were able to accumulate long‐chain polyunsaturated fatty acids (PUFA), such as docosahexaenoic (DHA, C22:6n − 3), eicosapentaenoic (EPA, C20:5n − 3) and arachidonic (ARA, C20:4n − 6) acids, either by assimilation and retention of dietary FA or by the synthesis from α‐linolenic acid (ALA, C18:3n − 3) and linoleic acid (LA, C18:2n − 6). Furthermore, the low DHA/EPA ratio and high EPA/ARA and n − 3/n − 6 ratios of Rho and Chae and the high levels of the β‐carotene present in Chae improved larval growth and development. In conclusion, the results indicated that of the three microalgal diets tested, C. calcitrans provided important nutritional characteristics, especially in terms of FA composition and carotenoids, improving P. lividus larval growth and condition.

Changing the biochemical composition of microalgae by tuning physical and nutritional parameters leads to similar changes in the biochemical composition of microalgae-fed organisms, both at the larval and adult stages [32,33].…”

Highly Valuable Polyunsaturated Fatty Acids from Microalgae: Strategies to Improve Their Yields and Their Potential Exploitation in Aquaculture

Microalgae have a great potential for the production of healthy food and feed supplements. Their ability to convert carbon into high-value compounds and to be cultured in large scale without interfering with crop cultivation makes these photosynthetic microorganisms promising for the sustainable production of lipids. In particular, microalgae represent an alternative source of polyunsaturated fatty acids (PUFAs), whose consumption is related to various health benefits for humans and animals. In recent years, several strategies to improve PUFAs’ production in microalgae have been investigated. Such strategies include selecting the best performing species and strains and the optimization of culturing conditions, with special emphasis on the different cultivation systems and the effect of different abiotic factors on PUFAs’ accumulation in microalgae. Moreover, developments and results obtained through the most modern genetic and metabolic engineering techniques are described, focusing on the strategies that lead to an increased lipid production or an altered PUFAs’ profile. Additionally, we provide an overview of biotechnological applications of PUFAs derived from microalgae as safe and sustainable organisms, such as aquafeed and food ingredients, and of the main techniques (and their related issues) for PUFAs’ extraction and purification from microalgal biomass.

“…In husbandry, the ovarian activity of goats is also improved when fed with Dunaliella-supplemented feed, hastening the follicular development [12]. In aquaculture, living Dunaliella cells are mostly used as feed ingredients, and sea urchins can efficiently incorporate Dunaliella protein into their larvae [13]. These examples show that studies on the practical applications of Dunaliella protein are indeed very scattered.…”

β-carotene production with Dunaliella microalgae is established, yet their potential as protein source for food and feed applications seems overlooked. The rich protein content and nutritional tunability of Dunaliella make these algae intriguing sources of sustainable protein. It is of societal interest to exploit these promising proteinaceous Dunaliella traits. Dunaliella microalgae: Spotlighted β-carotene and undervalued protein Microalgae are recognized as promising sources for diversified applications including food, feed and high-value products [1]. Both science and industry have already focused their interests on Dunaliella microalgae, especially for their unique feature of hyper carotenogenesis, producing
